Abstract
A coil forming apparatus includes a twisting formation unit that twist-forms a predetermined number of U-shaped conductor segments. The twisting formation unit includes a first twisting formation jig composed of a first inside ring and a first outside ring and a second twisting formation jig composed of a second inside ring and a second outside ring. Each of the first and second inside rings has the same number of circumferentially disposed holding slots as the stator slots to hold one of each pair of straight portions. Each of the first and second outside rings has the same number of circumferentially disposed holding slots as the stator slots to hold the other of each pair of straight portions of the U-shaped conductor segments. The first and second inside rings and the first and second outside rings are coaxially coupled to shift relative circumferential position between the inside rings and the outside rings by a predetermined angle to twist the turn portions of the U-shaped conductor segments.
